ABSTRACT
Objective To investigate the relationship of triglycerides/high-density lipoprotein (TG/HDL C) ratio with coronary heart disease (CHD) and its severity.Methods 158 patients with CHD were enrolled in this study.Patients were divided into 4 groups according to the selective coronary arteriography:the control group,single-vessel CHD group,double-vessel CHD group,multiple-vessel CHD group.The relationship between multiple risk factors and CHD was analyzed by stepwise multiple regression.The severity of coronary artery stenosis was analyzed by Gensini scoring system.Results TG/HDL-C ratio was elevated in patients with coronary artery stenosis as compared with the control group [(1.8±1.0) vs.(1.7±1.4),t=2.68,P＜0.05].TG/HDL-C ratio was elevated along with the severity of CHD.TG/HDL-C ratio was elevated in multiple-vessel C HD group as compared with the control group by ANOVA analysis (P＜0.05).Stepwise multiple regression showed that multiple-vessel CHD was positive related with total cholesterol (TC),LDL-C and TG/HDL-C ratio (β value:0.326,0.339,0.158,respectively,all P＜0.05).Conclusions TG/HDL C ratio is related with multiple vessel CHD,but it does not have more clinical significances than other indicators.
ABSTRACT
Objective To investigate the serum uric acid level in isolated systolic hypertension (ISH)in the elderly, and effect of Losartan potassium. Method Serum uric acid level were assessed spectrophotometrically using enzy matic methods in 85 ISH patients and 51 health controls. Serum uric acid level and blood pressue were compared respectively before and after the treatment of losartan potassium and Benzepril. Result Uric acid levelwas higher in patients with ISH than that in control group (P ＜ 0.01 ) . No significant difference was found between Losartan potassium and Benzepril group on the effect of lowering blood pressure. After antihypertensive treatment, uric acid level in Losartan group was significantly lower than that in Benzepril group(P ＜ 0. 01 ). Conclusion Uric acid level was marked higher in ISH in the elderly; Losartan prtassium has an additional benefit of some uricosuric effeets besides the antihypertensive effect.
ABSTRACT
Objective To explore the relationship between insulin resistance (IR) and plasma tumor necrosis factor ?(TNF ?) in patients with congestive heart failure (CHF) in the elderly. Methods The levels of fasting plasma insulin (FINS) and TNF ? were determined by means of radioimmunoassay in 52 elderly patients with CHF and 36 elder healthy controls. Insulin sensitivity of CHF patients was assessed using reciprocal of the product of fasting plasma insulin and glucose (IAI). The correlation between the grades of cardiac function, left ventricular ejection fraction(LVEF) and IAI of the CHF patients and TNF ? were analyzed. Results Compared to the elder healthy controls, elder patients with CHF showed significantly higher levels of TNF ?〔(0 36?0 13) ?g/L vs (0 21?0 12) ?g/L, P
ABSTRACT
Objective To study the detection method of insulin resistance in congestive heart failure.Methods Levels of fasting plasma insulin and glucose were determined in 41 patients of CHF and 26 normal controls through radioimmunoassay.The application value of the inverse of the product of fasting plasma glucose and insulin (IAI) and the ratio of fasting plasma glucose and fasting insulin (FPG/FINS) were compared.Results IAI levels in patients with CHF were significantly lower than those of the control group(P
